제품 설명

Eosin Y (Acid Red 87 free base) is a soluble acid red dye molecule. Eosin Y has a wide application in organic synthesis as a photoredox catalyst[1].

In Vitro

Eosin Y is widely applied as a photoredox catalyst in organic synthesis[1].
Eosin Y finds application in cell staining, as a pH indicator, as an indicator in the analytical halide determination by Fajans and as a dye pigment, e.g. in lip sticks[1].
Eosin Y is the most widely used counterstain in routine staining of histological tissue sections (erythrocytes, collagen, epithelial cells, etc.)[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
